GFS2: Log the reason for log flushes in every log header
This patch just adds the capability for GFS2 to track which function called gfs2_log_flush. This should make it easier to diagnose problems based on the sequence of events found in the journals. Signed-off-by: Bob Peterson <rpeterso@redhat.com> Reviewed-by: Andreas Gruenbacher <agruenba@redhat.com>
